5 a new and useful Improvement in Connect- I ing and Spacin 'ClipsforMetal Reinfor'ce ment and the Llke; and I do hereby declare;

the following to he a full, clear, and exact description thereof.

1. This invention relates to'a connecting and --spacn1g member or clipfor the metal rem- -.-.forcement for concrete, cement, beton and similarstructures or' for heavy 'metal fences or the like.

5 ;=The object-of the-invention is to" provide a device for the purposestatedfwhich is simple "-andichea "to manufacture, which can heaplied int e field'witha minimum amount of' abor, which holdsthe parts firmlyin'contact and-225 7 9 P tion; and"whichisso con- ,2 struc v that thepo'sition of the connected members can bereadilylcllanged.

i Many concrete and cement constructions 1 are reinforced by means ofmetal rods, bars,

.25 stri s or,- the like; extending both "longitudicrossing each other.

nal ymnd -transverse'lk for vertically, thus i'ly device adapted-es'pecia y for-connecting andholding such crossing reinforcing members.The device A is so constructed that it holdslthese members rigidly andfirmly in position, but in a man- -ner to permit their adjustment ifnecessary, and at the same time serves to space the crossingmembersfrom' the centering or casin soils to position thereintorcementproper y in the concreteflas well as to insureits entire envelopment bythe c ncrete.

:The invention consists'ofa device of the character heremafter describedand clamnxl.

Figs. 5 and 6 showone of the crossing members as a fiat strip or band, such as used incolumn constructions. All of the forms can be used for connecting anycrossing members,

the gerp:ojecting oppositely to thelimb.

either for floor, ceiling, wall, partition or column constructions.Figafl; 8 and-9, l1ke'Figs.5 and 6, show a construction such as can beused in columns,

tanks and the like, having the vertical orcompression rods 17 and thetransverse bands 18 connected together by clips 3", which may be such asheretofore described. In these views, the clips are slightly modified,having the edge notches 19 with tongues 20 at the 0 en sides to preventthe disengagement of t e clip and vertical rods. These clips may,

if desired, have the outwardly projecting fingers or tongues 7, as shownin .ig. 9 and the other views, or may have aseparate piece eitherin'a Uform 7, Fi 8, or ma loop, 7', as shown in'Fig. 7, an which serves as a scing member to contact with the casing. 'fiLlS se arate piece is shownas held between the b0 y of the clip and the band," so that it '45cannot get out of place while being erected or while the concrete isbeing filled around the reinforcement.

The devices described are very sim le of construction, can be made fromor inary sheet orband metal'by ordinary unching and bending operations,and can e easily applied inthe field. These devices firmly grasp thecross' members and bind them tightly together, ut nevertheless in aman-' ner which permits the relative ositions of the crossing memberstobe readl y changed. The connecting members also serve'as spacin members.I

7. A connector for crossing metal melnbers, comprisinga clip providedwith a loop to engage one oi-the crossing members and having limbsprovided with alining' openings to receive the other crossingmember,.one or both of said limbs being extended to contact with thecentering or casin and a-portion of the loop being arranged tobebent andforced against one of the crossing members.

8. A connectorior reinforccment for con- 'crete work, comprising a'flatmetal plate bent to U shape to provide a loop to embrace onereinforcement member and having its limbs provided in their side edgeswith openings or notches for receiving and retaining anotherreinforcement member at right angles to the first member, andhaving anoutwardly extending'projection for contacting with the centering orcasing. I

9. A connecting member for reinforcement for concrete work, comprisingaclip provided with a loop to embrace a reinforce ment 'member andhaving a limb or limbs provided in their side edges with openings ornotches to receive and retain another reinforcement member at rightangles to the first member, and having an outwardlyprojecting finger orfingers arranged to contact with the casing.
